Upgrade crafting modifier count by tier
A Steam Community guide reports two or three guaranteed upgrade modifiers, with additional modifiers at advanced, superior, and extreme tiers.
How it works
The author says crafted upgrades have two or three guaranteed mods, then one extra for each tech tier beyond standard: one at advanced, two at superior, and three at extreme. This is a player guide's report, not independently corroborated by the other supplied source. It gives no upgrade costs or probabilities for specific modifier combinations.
